Measure generated application startup and publish footprint

## Objective

Compare generated basic and Hybrid applications against current templates for startup, memory, working set, file/assembly count, publish size, handles, and shutdown. Use the results to keep defaults lean and document the cost of optional features.

## Completion guidance

- Keep the implementation focused on the objective while allowing the assignee to improve the approach based on research.
- Document important decisions, rejected alternatives, dependencies, and follow-up work.
- Add or update tests and documentation appropriate to the work.
- Verify locally and in CI where the task changes code or generated artifacts.

The issue names generated basic and Hybrid applications and current templates, but no files, tests, or entry points. Start by locating those generated application templates, then establish how to measure startup, memory, working set, file and assembly count, publish size, handles, and shutdown; done means documented comparisons, decisions, and appropriate verification.
